The Theoretical Thinking of Engels on Historical Materialism,Russian Social Development and Methodological Principles in His Later Years
Since Marx's death,Engels has shouldered the heavy responsibility of defending and de-veloping Marxism.In his letters to Conrad Schmidt,Joseph Blosh,Franz Mehring and Walther Bor-gius,Engels elaborated a series of important ideas related to the materialist conception of history.In"Postscript to'On Social Problems in Russia'",Engels thought deeply about and reinterpreted the question of the path of social development in Russia.In his later years,Engels adhered to and devel-oped the materialist conception of history,studied the social problems of Russia from the viewpoint of the materialist conception of history,and put forward the methodological principles of Marxism,which demonstrated his intellectual wisdom and theoretical charm.
